[TenTec] Omni VII Query

[Val Erwin]

Good Morning Group.......
 
Regarding my earlier E-mail (below)  to the group on my low RF power output (85W) from my Omni VII, I have determined the following after trying several of your furnished thoughts/ideas:
 
* One of you suggested that one of the Molex pins in the DC power connector cable might be a little loose and causing a voltage drop. Sure nuff', the positive pin was slightly deformed and the pin was replaced and power increased but only by appx. 3 watts.
 
* I contacted Stan Brock at T-T via E-mail and he advised I contact Garry Green, the tech at T-T that works on the Omni VII.
 
* This morning, I spoke with Garry Green on the phone and he advised me that early on in production, several Omni VIIs went out the door with the RF power set on the low side. (This does not explain why mine measured 105 watts when it was new.) Garry explained that if I would send in my Omni VII, he will reset the power output. He also explained that there is not a single control that sets the RF power output. As it turns out,resetting the RF power is not all that simple as the operation is contained within software/firmware and requires setting the RF power on EACH band!
 
Thus, I will send my Omni VII back to Garry at T-T after the XMAS package traffic rush dies down.......using my Jupiter in the interim.....
 
TNX AGN for all your ideas.......

Omni VII-ites'
 
I have an Omni VII that is appx. 2 years old. Over time, I have noticed a gradual decrease in RF output power. 
 
With 13.8 VDC measured at the radio power connector, the Omni VII digi-panel states: "Power 100W".  Yet, when the RF output power is measured with a lab-grade 50-ohm load and either a Bird 43 or a calibrated oscilloscope, the measured RF power is actually on the order of 85 watts output, regardless of band.
 
I suspect I have an aging component sitcheeashun'..........Is there an internal control to crank the RF back up to spec??
 
TNX in advance for any feedback.........
